The experiment was carried out to standardize number of pheromone traps required for mass trapping of pink bollworm at Sapa and Mangrol village of Karjan taluka of Vadodara district, Gujarat during Kharif, 2016-17 and 2017-18, respectively. There were total five treatments i.e. 30, 40, 50 and 60 traps/ha including control with 15 repetitions. Among all the treatments installation of 40 pheromone traps/ha, 30 cm above crop height at equidistantly one week prior to flowering and changing the lure at one month interval till last picking of Bt cotton is found effective and economical for management of pink boll worm, Pectinophora gossypiella in Bt cotton.
